Dewey

Dewey is quieter and more inclined to the arts than his brothers. He hides his intellect from Malcolm and Reese, in many cases cleverly taking advantage of them.

ERIK PER SULLIVAN
Erik Per Sullivan began acting at age five when his father took him to an open casting call for "Armageddon." After appearing as an extra, Sullivan won his first credited film role in the Oscar-winning film adaptation of John Irving's "The Cider House Rules." Along with his role on "Malcolm," Sullivan continued to work in movies like "Joe Dirt" where he played the young David Spade character. He also voiced Sheldon the Seahorse in the gigantic hit, "Finding Nemo."
